Rather than having the user pass in name and quantity, have the user pass in a Grocery. You complete throw away any sense of encapsulation by having the user provide the components rather than the object.

Hah. Especially in C++. There's a particular interesting talk (if you're into cache-y type things) by Stroustrup where he compares a vector to a list and basically concludes that lists suck even when logically/algorithmically a list is what you think you need.

@Jamal Yeah, I thought about prefixing my post with a note about how I knew you probably knew a lot of what I was going to say. I tend to review all programs as if they were real programs though. Otherwise, everything really comes down to "tl;dr: it doesn't matter in a one off, toy program." :D

I might post my list, but it's a bit less toy-ish and more... massive. It's only about 75% finished and I'm afraid it's already probably too long for CR. github.com/nibroc/containerpp/tree/dev. I will likely post it at some point after I go through and refactor it heavily. I've never posted anything before, and I'm a bit curious what bad habits/design pitfalls/etc I have.

@Yuushi Hrmm, perhaps when I get a chance in a few days, I'll clean it up and post it.

@Jamal well, ideally an container should have no idea (nor care) what it's storing, so it would be completely separate from the container. In this case though, since the list is special purpose, that doesn't really apply. I would have the list keep using Grocery (rather than going the templated route), and just pull Grocery out into its own header (e.g. Grocery.h) and maybe implementation file if you give it methods.

It just feels icky to use a string/number pair since it's both vague and prone to break when changes are made (Like what if you wanted to add a cost field to Grocery? Then you would have to update all of your methods).

I'm looking for a more cleaner and simpler solution to auto-format a text-box field intended only for the user to enter their college Grade Point Average (GPA). Here is my code:

I think the day the average upper management no longer sees code quality, peer reviews, refactorings, readability, extensibility and all of SOLID as something that costs more and delays delivery, but rather as something that reduces total costs and only adds positiveness in every single possible aspect of a project, that day, ...pigs will fly.

well of course if you're talking about overall maintenance in specific languages or technologies, ...thing is, maintenance doesn't diminish overall - the only thing that changes is the language of the code being maintained..

if anything that demand will (hopefully) increase over time; more time, more programmers; more programmers, more code; the more code there is, the more there's code to maintain - the more jobs we have ;)

Inspired by all of the lovely linked lists lately, I decided to implement one in assembly language. This code maintains two linked lists - one is a free store and the other is the active linked list. Rather than allocating memory whenever a new node is needed, the Node is pulled from the free l...

@Sham I think that's specific to how each company runs their stuff.. you can find a job where you land in a team of 3 devs that each work in their own "silos", or you can land in a team of 3 devs that work as a team, and have a team lead that reports to some IT director. The maintenance team is often the dev team and the test team.

I wrote a stack implementation using a singly linked list in x86_64 assembly. This stack supports the usual push/pop operations as well as first/next for iterating over each element.

@Corbin: I have made some massive changes to the code, including removing some member functions. I've probably rushed my implementation a bit, and you have pointed out some of the biggest things, so I may accept your answer soon.

@Jamal I apparently forgot it too. What do you mean about removing them in C++11? If there's some kind of resource management going on, they're still very much required (and it becomes the rule of 4 or 5 in some circumstances if moving is involved).

You need to consider the Rule of Three.
That is: the default copy and assignment implementations will not handle the head as you'd like. You need to define them correctly, or hide them (or remove them in C++ 11).
For example:
class LinkedGroceryList
{
private:
LinkedGroceryList(const Linke...

@Jamal I don't think he meant remove them as in "or you can just not have them." I think he meant it in the sense of "if you want to disable copying and assigning, you can T(const T& t) = delete; them." You do either need to implement them or delete them though.

I just wrote this pool to avoid calling malloc and free when I have some code that frequently allocates and deallocates chunks of same-sized memory. I would like to know if there are any bugs I didn't notice and what would be the best solution to achieve this goal.

@Jamal If you're inserting before some existing item in the list, you'll move the pointer to that existing item into your new items' next pointer. If you're adding to the end of the list, its next pointer will be a nullptr.

Keep in mind that unique_ptr's are unique. They own the underlying object. tail is (apparently) intended to refer to the last item in your list. If so, it can't be a unique_ptr (that would imply its owning the last item in the list, which is already owned by the unique_ptr in the previous node). As such, tail should be a normal pointer, and should just point to the last item in the list. When you insert into an empty list, both head and tail will refer to the one node in the list.

When you add more nodes, head will still refer to the first, and tail to the last.

If memory serves, I'd done deleting by swapping to a local variable (that goes out of scope and deletes the item). So, to delete the first item in the list, you point your local variable to the second node in the list, then swap it with the head of the list. That gives the head of the list ownership of the remainder, and it ownership of the first element. Then when the function exits, it automatically deletes that first element.

For something other than the head of the list, you're swapping with the pointer in the previous node that points to the node you want to delete.

It was suggested to me that I should post this Stack Overflow post over here.

somebody had asked same type of question on stakeoverflow.com and than he was suggested by some expert that he needs to ask such question on codereview.stackexchange.com. So I asked this question here . May I know what is wrong in it ? — KRC47 mins ago

xkcd, sometimes stylized as XKCD, is a webcomic created by Randall Munroe. The comic's tagline describes it as "a webcomic of romance, sarcasm, math, and language." Munroe mentions on the comic's website that the name of the comic is not an acronym but "just a word with no phonetic pronunciation".
The subject matter of the comic varies from statements on life and love to mathematical and scientific in-jokes. Some strips feature simple humor or pop-culture references. Although it has a cast of stick figures,
the comic occasionally features landscapes, intricate mathematical patterns su...
